The zirconia was developed and processed by VITA and is described as Zirconia Block. The zirconia has high mechanical properties and prevents cracks from extending. The zirconia is very useful material because it has a convenient mechanism and allows occurrence of expansion by switching to monolithic phase. The CAD/CAM technology, which generates a compression fore, was first used in 1988. The CAD/CAM technology requires using a milling machine through computer software and is based on production of composite, metallic block crowns and ceramic. The conventional dental impression is eliminated by the CAD/CAM technology which aims at having short period of time and also supports the elimination of preparation of temporary crowns.
This systems also saves on time for the laboratory technicians and the CAD/CAM software is designed via restorations. The CAD/CAM technology is indispensable for clinical success and makes the things different with its robust substructure. The materials used for the CAD/CAM system are milled in a very short period of time and protected against damages. In the CAD/CAM technology used, the restorations can be made in order to have a physical image. The CAD/CAM technology has the leading position among the methods that are commonly used in recent years and uses silicate-based ceramics. The CAD/CAM technology is used for the restoration of one tooth as well as for the laminate veneer and inlays. After optical dental impression is taken and the teeth are prepared, then you may proceed with other processes. In the CAD/CAM technology, fist an access path needs to be identified, and the suitable tooth preparation should be selected. In the adhesive restoration process used, standard principles are different. You may use the CAD/CAM technology to have a long desired smile in the very short period of time.
